Lemon Blueberry Poke Cake
This paleo lemon blueberry poke cake features a bright lemon glaze and a tender, grain-free crumb. The recipe can be made paleo or adjusted for low-carb and keto diets while remaining gluten-free and naturally flavorful.
This cake is perfect for anyone who wants a citrus-forward dessert that is lighter on refined sugars and grains without sacrificing taste.
Paleo Lemon Blueberry Poke Cake is easy to prepare and reliably delicious. It combines the bright tang of lemon with optional juicy blueberries and a silky lemon glaze that soaks into the cake through the signature “poke” holes. The result is moist, aromatic, and crowd-pleasing—great for family gatherings, potlucks, or a simple weekend treat.
My mother used to make a lemon poke cake when I was growing up in the 1970s. The name comes from the classic technique of poking holes in the baked cake and pouring glaze over the top so the flavor seeps in. I modernized her original recipe by swapping refined flour and powdered sugar for paleo-friendly ingredients and adding optional blueberries for a burst of antioxidants.
If you prefer, leave out the berries and make a straight lemon poke cake—the glaze and lemon flavor are outstanding on their own. This cake adapts well to different sweeteners: use paleo sweeteners like honey or maple syrup, or choose low-carb alternatives for a keto-friendly version.

Course: Cake, Dessert | Cuisine: American
Servings: 9 | Calories: 130 kcal (low-carb estimate)
Ingredients
- Cake
- ½ cup coconut flour, sifted
- 3 eggs, beaten
- ⅓ cup unsweetened coconut milk or almond milk
- 2 tablespoons lemon juice (fresh)
- 1 tablespoon lemon zest
- 2½ tablespoons coconut oil
- Sweetener of choice: ⅓ cup organic maple syrup or honey; for low carb use ⅓ cup low-carb maple syrup + ⅓ teaspoon liquid stevia
- 1 teaspoon lemon extract (organic, gluten-free)
- ½ teaspoon baking soda + 1 teaspoon apple cider vinegar (mixed together until fizzy)
- ½ cup blueberries (optional)
- Lemon Ice Glaze
- 2 tablespoons coconut oil or butter, melted
- 1½ tablespoons coconut butter, melted
- 1½ tablespoons unsweetened coconut milk
- 1½ tablespoons lemon juice
- ½ teaspoon lemon extract
- 2 teaspoons lemon zest
- Sweetener: 1½–2 tablespoons honey for paleo; for low carb use 2 tablespoons erythritol or ⅓ teaspoon liquid stevia
Instructions
- Preheat the oven to 350°F (175°C). Grease or oil a 9-inch round cake pan.
- In a large bowl, combine the coconut flour, beaten eggs, coconut milk (or almond milk), lemon juice, lemon zest, coconut oil, sweetener, and lemon extract. Stir thoroughly, breaking up any coconut flour clumps.
- Mix the baking soda and apple cider vinegar in a small bowl until very fizzy, then fold that mixture into the batter.
- Gently fold in the blueberries if using.
- Pour the batter into the prepared pan and spread it evenly.
- Bake for about 30 minutes, or until the cake’s center feels firm and a toothpick comes out clean.
- Remove the cake from the oven and let it cool for 10 minutes while you make the glaze.
- For the glaze: warm the coconut oil (or butter) and coconut butter in a small saucepan over low heat until melted. Remove from heat and whisk in the coconut milk, lemon juice, lemon extract, lemon zest, and sweetener until smooth. Allow the glaze to cool slightly so it thickens a bit but remains pourable.
- Use a skewer, metal skewer, or large toothpick to poke holes all over the cake, reaching down to the bottom.
- Pour or spoon the lemon glaze over the top of the cake, making sure it seeps into the holes and evenly covers the surface. Use the back of a spoon to spread the glaze if needed.
- Let the cake cool and allow the glaze to set for about 5 minutes, or until slightly firm.
- Slice and serve. Store leftovers in the refrigerator.

Storage and Serving Tips
Keep any unused cake refrigerated. Serve slightly chilled or at room temperature. This cake pairs well with a dollop of unsweetened whipped coconut cream or a scattering of extra fresh blueberries for garnish.
Variations
- For a lemon-only version, omit the blueberries.
- To make this fully keto, replace honey or maple syrup with erythritol and add a touch of liquid stevia if needed for sweetness.
- Try almond flour blends cautiously: coconut flour absorbs more liquid, so substitutions require recipe adjustments.
